The purpose of the utility model is realized like this:

the utility model provides a cross-type microchannel liquid cooling plate, includes communicating pipe and leads to liquid cooling pipe a little, and a plurality of logical liquid cooling pipe vertically and horizontally staggered become the grid form a little, and every grid node is equipped with two communicating pipes that intersect from top to bottom, the middle part of communicating pipe is equipped with dodges the groove, and the both ends of every communicating pipe are connected respectively and are led to liquid cooling pipe a little.

Preferably, two communicating pipes located at the same grid node are vertically crossed, wherein an opening of an avoiding groove of one communicating pipe faces upwards, and an opening of an avoiding groove of the other communicating pipe faces downwards.

Preferably, the junction of communicating pipe and little logical liquid cold tube is equipped with the tang structure, both ends are equipped with the tang about communicating pipe, the tip that leads to little liquid cold tube corresponds the tang and is equipped with dodges the opening.

Preferably, the micro-through liquid cooling pipe is divided into a plurality of cooling channels by partition plates, and a distance is reserved between the partition plate at the same end and the micro-through liquid cooling pipe to form an avoiding opening.

Preferably, the length of the seam allowance is greater than that of the avoidance opening, and after the avoidance opening is spliced with the seam allowance, a gap is reserved between the end part of the avoidance opening and the root part of the seam allowance, and the gap is a.

Preferably, the gap a is fixed by brazing.

The beneficial effects of the utility model are that:

1. the stability of the whole structure can be improved, and meanwhile, the mutual extrusion of each battery cell can be avoided when each battery cell is loaded, so that the product safety is improved.

2. The grid structure can restrain the position of the battery cell, so that the battery cell can be conveniently mounted, and the assembly efficiency is greatly improved.

3. The avoiding opening on the liquid cooling plate can play a role in pre-positioning, so that the liquid cooling plate is convenient to mount.
